Advance timing lights are a no-no.

I've used a Snap-on advance timing light for all of the years that I've been racing with almost every type of MSD ignition system. I haven't had any problems.

I never use timing lights with an advance feature, don't trust them. I like the self battery powered units. Simple.

Adjustable advance timing lights are not recommended for use on MSD ignitions. Plenty of information/confirmation out there with a little Goggleing.

MSD sells their own light, both 12v and self powered - or - you can try to find an old Ferret/MSD non-adjustable light - or - you can pick up a mint or NOS Sears/Penske 2138 light, this was sold relabeled by MSD years ago under part #8990. This is what I've used for decades. They are out there.

I've seen people say they've had good results with some of the self-powered lights (Flaming River, etc) available as well, but have no personal experience with them.

Whatever happened to increasing the timing until it showed on the timeslip no gain or you're going slower? Who really cares about the actual number? Get it to crank, idle, and go down the track.

A cheap Sears light or similar to get it fired and close and then tune it.......

If you can't afford a good damper (balancer) then put the timing tape on there. I don't own a dial-back light, never have.

Ya know, I know a guy who used to run comp cars and gassers WAAAAY back in the day (he's well into his 80s) and he set his timing by lining up his timing mark on the balance at the timing that he wanted, turning the ignition on and moving the distributor until the points (remember them?) sparked. After that, he would move the distributor back-and-forth until the ET slip was happy.
